Orange LED flashing slow fast means what?

Hardware Nano Family Nano RP2040 Connect
1

I've googled and read datasheets and can't find a thing about the orange LED (DL2).

It's flashing 4 times slow then 4 times fast. (and repeating)

Anyone know exactly what this means? Is it just "I've crashed!"?

Is this in your car or bicycle or where?

Well it says [Hardware][Nano Family][Nano RP2040 Connect] right under the post title. So, I'm guessing it's on a Nano RP2040 Connect?

4

what did you do to cause this?

Do you know how many people post under the wrong category each day? Lots!

Ran some code that's not working.

I was only asking about the orange slow/fast blinking. Just need confirmation that it just means crashed, and wondering if there are other patterns meaning different things.

But perhaps I should expand...

I'm trying to get a ST7735 based display working on RP2040 Connect using TFT_eSPI.

#define TFT_MOSI PIN_SPI_MOSI
#define TFT_SCLK PIN_SPI_SCK
#define TFT_CS   10  // Chip select control pin D10
#define TFT_DC   8  // Data Command control pin
#define TFT_RST  19  // Reset pin 

#include <Arduino.h>
#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
    Serial.begin(9600);
    while (!Serial);
    Serial.println("Setup Start...");
    //Serial.flush();

    tft.init();
    Serial.println("tft.init();");
    tft.setRotation(3);
    tft.setTextSize(1);
    tft.setTextColor(TFT_YELLOW);
    tft.drawString("hello world", 0, 0);
}

void loop() {
// write your code here
}

It's crashing in arduino::MbedSPI::beginTransaction (from TFT_eSPI::init), specifically on a call to mbed::SPI::format for which I can't find the source, think it's in a compiled lib?

void arduino::MbedSPI::beginTransaction(SPISettings settings) {
    if (settings != this->settings) {
        Serial.println(dev != nullptr);                                        // my diagnostics
        Serial.println(dev->obj != nullptr);                               // my diagnostics
        dev->obj->format(8, settings.getDataMode());             // CRASH here
        Serial.println("GOT HERE3");                                        // my diagnostics
        dev->obj->frequency(settings.getClockFreq());
        this->settings = settings;
    }
}

Welcome to the forum.

It is likely in the libmbed.a file. See

C:\Users\UserName\AppData\Local\Arduino15\packages\arduino\hardware\mbed_nano\2.4.1\variants\NANO_RP2040_CONNECT\libs

Yes, its the mbedOS crashed signal. I am not aware of other patterns. You can get some more information from the hardware serial port when mbedOS crashes.
